Find a flicker-safe shutter for 50 Hz or 60 Hz power
Open RIG, set Mains to the power where you are shooting, and read the Flicker-safe row. It always names a safe shutter for your frame rate, for example 1/50 is safe on 50 Hz power.
Step by step
- Tap the sliders button at the end of the strip under the reading to open RIG.
- Under CAMERA, set Mains to 50 or 60 Hz. Meter starts from your device's region, and in Japan it starts on 50.
- Read the Flicker-safe row. If your shutter is not safe, it names the nearest one that is.
- Set that shutter, or tap USE on the orange line when the meter shows one.
If that didn't work
A shutter is safe when it takes in a whole number of flicker cycles. Meter assumes lights on the mains flicker at twice the mains, 100 times a second on 50 Hz and 120 on 60 Hz. A light on a battery or its own driver can pulse at another rate, so test on the camera.
